Currently NixOS creates the swapfile (with the specified size) only if
it doesn't already exist. Changing the swapfile size afterwards will not
have any effect.
This commit changes that so the swapfile will be recreated whenever
swapDevices.*.size is changed (or more precisely, whenever the actual
file size differs from the configured one), allowing both growing and
shrinking the swapfile.
The service unit has "restartIfChanged = false", so we don't have to
worry about the swapfile being in use at the time this code is run (you
have to reboot for swapfile changes).
fallocate doesn't shrink files, use truncate for that. truncate can also
be used to grow files, but it creates "holes" in the file which doesn't
work with swapfiles.
The test runner would import all modules to check whether they might
have tests.
On a Linux system it would load the Tornado module that depends on
kqueue, which is BSD only, and fail.
':' is currently used as separator in /boot/grub/state for the list of
devices GRUB should be installed to. The problem is that ':' itself may
appear in a device path:
/dev/disk/by-id/usb-SanDisk_Cruzer_20043512300546C0B317-0:0
With such a path, NixOS will install GRUB *every* time, because it
thinks the configuration differs from the state file (due to the wrong
list split). Fix it by using ',' as separator.
For existing systems with GRUB installed on multiple devices, this
change means that GRUB will be installed one extra time.
I've realized that publishing updates to Hackage is far easier than
publishing updates in Nixpkgs, and since all Hackage updates show up in
Nix automatically I've decided to go back to publishing cabal2nix on
Hackage again.
Unfortunately, this means that I'll have to change the version numbering
scheme to comply with the expectations of the Haskell PVP (which is used
by Stackage), so the new version 2.0 looks like a downgrade to Nix,
which used to have version 20160406. :-(
If in doubt, run "nix-env -u --always" to force the update. I am sorry
about the inconvenience.
